RADIATOR.

. SPECIFICATION forming part of Letters Patent No. 679,920, dated August6, 1901.

Application filed January 2, 1901- Serial No. 41,759,. (No model.)

To all whom it may concern:

Be it known that I, ADOLPH STADEL, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Radiators,of which the following is a fulland complete specification, such as willenable those skilled in the art to which it appertains to make and usethe same. V

This invention relates to radiators for use in connection with steam orhot-water heating systems; and the object thereof is to provide animproved radiator for this purpose which is simple in construction andoperation and which is so formed as to provide a continuous inclinedpassage for the water or steam from the point where it enters theradiator to the pointwhere it leaves it, a further object being toprovide a radiator in which no vents are necessary and in which thewater of condensation when steam is used cannot collect at any pointtherein, but will continually flow therethrough, a further object beingto provide a radiator in the use of which there will be no knocking 0rrapping or hammering, which constitutes one of the greatest objectionsto steam-radiators as now used; and with these and other objects in viewthe invention consists in a radiator constructed as hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which-- Figure 1 is aside elevation of a radiator constructed according to my invention, thebase and top portion of the radiator not being shown, said figure beinga side View of the radiator-coils only; Fig. 2, a plan view of one ofthe raidiator coils or loops which I employ; Fig. 3, an end view of Fig.1 looking in the direction of the arrow 0,, and Fig. 4 a view of acoupling which I employ.

In the practice of my invention I provide a radiator which consists of aplurality of separate oblong loops 5, preferably of the form shown inFig. 2, but the form of which may be varied to considerable extent, andthese loops are divided atone end, as shown at 6, and one side thereofis raised and the other depressed. The depressed side of the top loop iscoupled to the raised side of the next loop thereunder, as clearly shownat 7 in Figs. 1 and 3, and this connection is made by means of a doublecoupling 8, (shown in detail in Fig. 4,) and the raised side of the toploop, the end of which is shown at 9 in Figs. 1 and 3, is used for aconnection with the steam or water supply pipe, While the depressed sideof the bottom loop, which is shown at 10 in Figs. 1 and 3, is used as aconnection for the discharge-pipe. By means of this construction it willbe seen that I provide a radiator having a continuousdownwardly-inclined passage from the point where the steam or waterenters the radiator to the point where it leaves it, and by means ofthis construction I also avoid the knocking or hammering whichfrequently accompanies the use of steam-radiators and I also avoid thecollection of water of condensation within the radiator, together withthe use of vents. The coils or loops 5 may be of any desired shape'suchas elliptical,circular,or oblongas shown in the drawings, and said loopsor coils may be of any desired shape in cross-section.

In a radiator of this class it is necessary to provide means forsupporting the opposite ends of the coils or loops and retaining them intheir proper relative position, and for this purpose I form on saidseparate coils or loops, at each end thereof, inwardly-directedprojections 12, provided with vertically-arranged sleeves 13, throughwhich are passed rods or bolts 14, which may in practice be connectedwith the top plate and base of the radiator in the usual or anypreferred manner, said top plate and base not being shown in thedrawings. The sleeves 13 may be of any-desired length, andby meansthereof the opposite ends of the loops or coils 5 may. be held in theproper relative position, and the radiator may also be made as strongand substantial as is necessary in articles of this class.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1.- A radiator consisting of a plurality of loops or coils arrangedhorizontally, said loops or coils being each divided at one end and oneside thereof being raised, and the other depressed, the depressed sideof one loop or coil being connected with the raised side of the loop orcoil thereunder, substantially as shown andidescribedi 2. A radiatorconsisting of a pliirality' of loops orcoils arranged horizontally, saidloops or coils being each divided at one end, and one side thereof beingraised, and the other depressed, the depressed side of one loop or coilbeing connected with the raised side of the loop or coil thereunder, theraised side of the top coil or loop and the depressed side ofthe bottomcoil or loop being adapted to serve as attachments fol-supply, and drainor exhaust pipes, substantially as described.

A radiator comprising a plurality of ob long loops or coils divided atone end and arranged horizontally, one side of each of said loops orcoils being raised at the divided end and the other side depressed, and;the depressed side of one of said loops or coils be- ADOLPH STADEL;
